W. Lll.i,Ji;i;t,)m'., 1S7<>. Tlif correctness of the determination ol thr lormer species was 

 veritied. For the result of my re-ex;unination of the latter form see tlic remark on the sub- 

 i.'enns Cypridina below. 



The collection sent to me liom the Z imi 1 o g i c a 1 M u s e ii m of (' ii r i s t i a n i a 

 included the following species: Ci/pridina (Vargida) norvegica ^^ . lUiiMi. ('. (Vargula) megalups 

 G. O. S-^l^'"*, Pfiilomcdes LiUjchoigi G. O. Sahs, Asterope norvegica G. (). Sahs, A. ahyssicola 

 G. 0. Saus, Couchoccia clcgans G. 0. Sars and C. borealis G. 0. Sahs, all of which were d(>ter- 

 inined by Professor Sai{S hiinst^lf. For the results of ray re-examination of this material see 

 the respective species below. (On tlie same occasion as this collection was sent to me Professor 

 Sahs informed me that the original material of his work of 1887 — which I asked permission 

 to investigate — had unfortunately been completely lost.) 



From the Copenhagen Zoological Museum I obtained a portion of the material 

 on which G. S. Brady based his treatise of 1902 a. The following marine sjiecies were found in 

 this collection (the names are those used in G. S. Brady's treatise): Asterope oculata, A. lichenoides, 

 Cyclasterope fa-scigera, C. brevis, C. similis, Cypridina foveolata, C. insolita, Pyrocypris americana, 

 P. Chierchiae, Cypridinodes favus, Codonocera cruenta, Conchoecia spinirostris, C. striata and 

 Eiiconchoecia Chierchiae. Of these species Asterope lichenoides, Cyclasterope brevis, Cypridina 

 foveol<Ua (according to G. S. Brady's label — Cypridina monopia Claus) anfl Codonocera cruenta 

 were represented by an empty shell and Cyclasterope similis, Cypridina insolita and Cypri- 

 dinodes favus only by one valve. Because of this I thought it best not to deal with these forms 

 at any length in this work. Asterope oculata and Cyclasterope fascigera are re-described by 

 me below. Conchoecia spinirostris (from lat. 26" N. and long. 29" W.) and Euconchoecia Chierchiae 

 were correctly determined; see these species below.* For the result of my re-examination 

 of Pyrocypris Chierchiae see the remarks on the sub-genus Cypridina below. For the same 

 reasons as are given at the place mentioned it did not seem convenient to me to deal in this 

 work with P. americana, the other species of this sub-genus; there are in this collection a couple 

 of mature individuals of this species. Conchoecia striata is presumably incorrectly determined, 

 but the material is so poor that it does not seem to be possible to arrive at a certain identi- 

 fication; I have accordingly refrained from trying to give any definite answer to the question 

 as to the identity of this form. 



Professor G. W. MUller kindly sent me at my request specimens of Cypridina 

 (Vargula) antarctica G. W. MOllei^ and Asterope teres (A. M. NORMAN); for the result of 

 my re-examination of these specimens see the former species below and my remarks under 

 Asterope Miilleri. 



For the purpose of carrying out a verificatory investigation I wrote to Professor G. S. 

 Brady for specimens of Asterope Mariae (W. Baird) and A. teres (A. M. Norman). I obtained 

 a mature female of the latter species; for the result of my investigation of this specimen see 

 Asterope Miilleri below. I also received five specimens of the former species; the result of 

 my investigation of these will be found under Asterope aberrata and A. norvegica below. 



* One specimen in the sample lalx'lled Conchoecia spinirostris was, hovvover, a mature female of V. bispinosa C. Claus ; 

 see this species below.
